1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The crosstalk between Ca(2+) and cAMP signals plays a significant role for the regulation of the endothelial barrier function. The Ca(2+)-elevating agent thrombin was demonstrated to increase endothelial permeability and to decrease cAMP levels. Since Ca(2+) and cAMP signals are highly dynamic, we aimed to study the temporal resolution between thrombin-evoked Ca(2+) signals and subsequent changes of cAMP levels. Here we conduct the first real-time monitoring of thrombin-mediated regulation of cAMP signals in intact human umbilical vein endothelial cells (HUVECs) by utilising the Ca(2+)-sensitive dye Fluo-4 and the fluorescence resonance energy transfer (FRET)-based cAMP sensor Epac1-camps. We calibrated in vitro FRET responses of Epac1-camps to [cAMP] in order to estimate changes in intracellular [cAMP] evoked by thrombin treatment of HUVECs. After increasing [cAMP] to 1.2 +/- 0.2 microm by stimulation of HUVECs with isoproterenol (isoprenaline), we observed a transient decrease of cAMP levels by 0.4 +/- 0.1 microm which reached a minimum value 30 s after thrombin application and 15 s after the thrombin-evoked Ca(2+) peak. This transient decrease in [cAMP] was Ca(2+)-dependent and independent of a G(i)-mediated inhibition of adenylyl cyclases (ACs). Instead the knock down of the predominant subtype AC6 in HUVECs provided the first direct evidence that the Ca(2+)-mediated inhibition of AC6 accounts for the thrombin-induced decrease in cAMP levels.
